Abstract: 

The collected data of ozone layer between 1979 to 1993 by TOMS sensor on board of NIMBUS-7, that have covered the earth atmosphere repeatedly, have made investigation of the change in the atmospheric ozone all over the world possible. The data used for this research have been confined into region between 47.5 E and 56.5 E longitude and 26.5 N and 38.5 N latitude. This region is from Macu in the north-east to the East of Bandar-Abbass in the south-east of Iran. The annual mean of the ozone has some fluctuations which can be explained by atmospheric circulation and industrial regions. This fluctuation tends to uniformity. The rate of the occurrence of this uniformity is noticeable in summer and fall. This uniformity also can more or less be seen in the industrial regions. The amount of ozone reduces in these two seasons. In the regions such as Alborz mountain, Ardabil province and the southern slopes of the Alborz, some anomaly in the amount of ozone can be detected but, it has not gone under the standard. As a case study, by Using MODIS images, the variation of the ozone layer in the atmosphere of Isfahan was evaluated by which, the aforementioned findings was approved.
